DP 7 (latest patch/version) on Windows 2008 R2 domain/servers, running a full filesystem backup of multiple servers
to MSL2024 G3 LTO5 tape library, two SAS tape drives .
Lately backup has become very slow and takes more hours than in the past.
Are there any Best Practices or a checklist I should go through to speed things up?
an upgrade to DP 9 is planned but not yet...
